A subscriber station configured to communicate with one or more base stations or other transmission points (TPs) in a wireless communication network is configured to receive, from the network, information associated with one or more of the TPs that are candidates for coordinated multipoint (CoMP) transmission with the subscriber station, to measure a plurality of channel quality values for each of the one or more TPs, and to report the measured channel quality values to the network.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for performing measurement in a communication system, the method comprising: receiving information associated with a measurement object from a base station, wherein the measurement object identifies a frequency and a channel state information reference signal (CSI-RS) information to be added for measurement, and wherein the CSI-RS information for measurement includes a CSI-RS identifier (ID), a physical cell ID information, and subframe information; performing measurement based on the CSI-RS information associated with the frequency indicated in the measurement object; and reporting the measurement to a base station if the CSI-RS becomes better than a threshold.
2. The method of claim 1 , wherein the CSI-RS information for measurement further includes CSI-RS information to be removed for measurement.
3. The method of claim 1 , wherein the measurement object further includes offset information.
4. The method of claim 1 , wherein the measurement is associated with reference signal receive power (RSRP), and is performed on a CSI-RS on antenna port 15 .
5. The method of claim 1 , wherein the measurement object includes a plurality of CSI-RS information in a list.
6. A subscriber station for performing measurement in a communication system, the sub scriber station comprising: a receiver configured to receive a measurement object from a base station, wherein the measurement object identifies a frequency and a channel state information reference signal (CSI-RS) information to be added for measurement, and wherein the CSI-RS information for measurement includes a CSI-RS identifier (ID), a physical cell ID information, and subframe information; a controller configured to perform measurement based on the CSI-RS information associated with the frequency indicated in the measurement object; and a transmitter configured to report the measurement to a base station if the CSI-RS becomes better than a threshold.
7. The subscriber station of claim 6 , wherein the CSI-RS information for measurement further includes CSI-RS information to be removed for measurement.
8. The subscriber station of claim 6 , wherein the measurement object further includes offset information.
9. The subscriber station of claim 6 , wherein the measurement is associated with reference signal receive power (RSRP), and is performed on a CSI-RS on antenna port 15 .
10. The subscriber station of claim 6 , wherein the measurement object includes a plurality of CSI-RS information in a list.
11. A method for employing measurement in a communication system, the method comprising: transmitting a measurement object to a subscriber station, wherein the measurement object identifies a frequency and a channel state information reference signal (CSI-RS) information to be added for measurement, and wherein the CSI-RS information for measurement includes a CSI-RS identifier (ID), a physical cell ID information, and subframe information; and receiving a report of a measurement from the subscriber station if the CSI-RS becomes better than a threshold, wherein the measurement is performed based on the CSI-RS information associated with the frequency indicated in the measurement object.
12. The method of claim 11 , wherein the CSI-RS information for measurement further includes CSI-RS information to be removed for measurement.
13. The method of claim 11 , wherein the measurement object further includes offset information.
14. The method of claim 11 , wherein the measurement is associated with reference signal receive power (RSRP), and is performed on a CSI-RS on antenna port 15 .
15. The method of claim 11 , wherein the measurement object includes a plurality of CSI-RS information in a list.
16. A base station for employing measurement in a communication system, the base station comprising: a transmitter configured to transmit a measurement object to a subscriber station, wherein the measurement object identifies a frequency and a channel state information reference signal (CSI-RS) information to be added for measurement, and wherein the CSI-RS information for measurement includes a CSI-RS identifier (ID), a physical cell ID information, and subframe information; and a receiver configured to receive a report of a measurement from the subscriber station if the CSI-RS becomes better than a threshold, wherein the measurement is performed based on the CSI-RS information associated with the frequency indicated in the measurement object.
17. The base station of claim 16 , wherein the CSI-RS information for measurement further includes CSI-RS information to be removed for measurement.
18. The base station of claim 16 , wherein the measurement object further includes offset information.
19. The base station of claim 16 , wherein the measurement is associated with reference signal receive power (RSRP), and is performed on a CSI-RS on antenna port 15 .
20. The base station of claim 16 , wherein the measurement object includes a plurality of CSI-RS information in a list.
